SAR Testing
The DASY is capable of evaluating products for SAR to all the global SAR standards for both head and body-worn devices.

MET Labs has the accreditation’s and experience to efficiently and cost-effectively perform Specific Absorption Rate (SAR) Testing up to 6GHz for the United States, Canada & Europe

MET’s SAR facility is fully equipped with a Schmid & Partner Engineering AG (SPEAG™) DASY professional system utilizing an RX 90 robotic arm for extended reaching capabilities. In addition, our DASY system has multiple twin SAM phantoms and planar phantoms which allows for quick testing turnaround times. The DASY is capable of evaluating products for SAR to all the global SAR standards for both head and body-worn devices.

MET tests an array of products such as Cellular/PCS GSM/DCS CDMA/GMSK/TDMA/AMPS phones, PDAs, Laptops, held-to-face devices, W-LAN (2.4GHz and 5GHz) and so on.

In conjunction with SAR testing, MET also performs Maximum Permissible Exposure (MPE) evaluations for fixed and/or mobile applications. These evaluations are performed on radiating structures that would be intended to be used at distances >20cm from the end user. Typical devices we test are vehicle-mounted antennas operating in the UHF and VHF bands.

SAR Testing Standards we test to:

IEEE STD 1528 IEEE – Recommended Practice for the Measurement and Computations with respect to Human Exposure to Radio Frequency Electromagnetic Fields, 100kHz to 300GHz.

EN 50364 – Limitation of human exposure to electromagnetic fields from devices operating in the frequency range 0 Hz to 10 GHz, used in Electronic Article Surveillance (EAS), Radio Frequency Identification (RFID) and similar applications

EN 50371 – Generic standard to demonstrate the compliance of low power electronic and electrical apparatus with the basic restrictions related to human exposure to electromagnetic fields (10 MHz – 300 GHz) – General public

EN 50385 – Product standard to demonstrate the compliance of radio base stations and fixed terminal stations for wireless telecommunication systems with the basic restrictions or the reference levels related to human exposure to radio frequency electromagnetic fields (110 MHz – 40 GHz) – General publicAs a Designated R&TTE CAB, which is a Notified Body, MET is authorized to review compliance in accordance with these standards as well as any other appropriate standards.

What is SAR testing?

Specific Absorption Rate (SAR) testing is the radiofrequency (RF) dosimetry quantification of the magnitude and distribution of absorbed electromagnetic energy within biological objects that are exposed to RF fields.

These levels are expressed as watts per kilogram (W/kg). International regulatory bodies are requiring SAR evaluations for most portable and mobile wireless technologies.

The FCC classifies a wide range of standalone independently-operated portable transmitters as being potential candidates for SAR testing. Laptop computers, for example, may require SAR testing. Handsets, pagers, and other devices that are worn on a belt can also require SAR testing. When portable transmitter antennas and radiating structures are less than 20 cm from persons, except extremities (hands, wrist, feet and ankles), and depending on the device’s frequency and threshold levels, SAR testing may be required.

About Eurofins | MET Labs

MET Laboratories, Inc was established in 1959 and has become a global service leader for product approvals and regulatory certification of electrical products in Baltimore, MD. In 1989, MET broke the UL monopoly for product safety testing and certification in the United States and is approved to certify products in over 200 UL standard categories. MET Labs is a service leader and trusted provider of product testing and regulatory certification of electrical products for leading brands and companies in the United States, Europe and worldwide. In 2018, MET joined the Eurofins Scientific network and has become a key component in Eurofins’ product testing portfolio.

About the MET Mark

The MET Mark for product safety is accepted throughout the United States & Canada and indicates compliance to federal regulations for safe use in the workplace. 30 years ago, MET became the first OSHA-recognized NRTL (Nationally Recognized Testing Laboratory) in the United States. The NRTL mark is required under federal law for products used in workplaces in all 50 states. MET listed products are also sold in every major retail stores throughout the United States and Canada.
